A technician is installing RAM in a desktop PC. The motherboard has four DIMM slots in two color-coded pairs. To enable dual-channel mode with two modules, where should they be installed?
Color-coded DIMM slots indicate channels. To enable dual-channel, install one module in each color group (e.g., one blue + one blue across the two pairs), not two modules in the same pair. Always check the motherboard manual for the recommended slots.
Which port is used by HTTPS for secure web traffic?
HTTPS uses TCP port 443. Port 80 is plain HTTP, 22 is SSH, and 3389 is RDP. Memorize the common port table - it shows up on every CompTIA exam.
A user reports that their laptop shuts down after 5-10 minutes of use. The fan is loud and the bottom of the laptop is hot. What is the MOST likely cause?
Loud fan + hot chassis + thermal shutdown = overheating. The most common causes on a laptop are dust-clogged vents and dried-out thermal paste. Clean the vents with compressed air and reapply thermal compound to the CPU/GPU.
Which cloud service model would BEST fit a developer who wants to deploy a Node.js app without managing the underlying servers or operating system?
PaaS (Platform as a Service) gives developers a managed runtime - they push code, the provider handles servers, OS, and middleware. Examples: AWS Elastic Beanstalk, Azure App Service, Google App Engine. IaaS would still leave them managing the OS.
A user's printout has vertical lines through every page on a laser printer. What component is MOST likely the cause?
Vertical lines on a laser printout indicate a scratched or damaged imaging drum. The drum repeats the same defect every revolution, which appears as a continuous line. Replace the drum (or full toner cartridge with integrated drum).
